Hi Linus,

This is the primary 4.7 pull.  There are a few more patches in the wings
but I'm not sending them yet.  There are a few known merge issues:

1) An mlx5 merge issue.  Two different patches both add new #include
directives in the same file.  This would have possibly been caught and
fixed up by our new working arrangement with Mellanox, but the patch I
took that induced the issue was an older one from the list that predated
the new working setup.  The fixup is a no-brainer, so I left it as is.

2) An NFSoRDMS merge issue.  The NFS tree has a cleanup patch that
touches the same for statement that one of our cleanup patches touches.
I've only got 2 lines of diff for the NFSoRDMA tree this time around and
we managed to get a conflict.  It's another simple fixup.

3) As per your comments a cycle or two ago, I used topic branches for my
work.  So if there's something you don't like in this pull request,
topic branches can be used to separate things out.  However, there are a
few patches that went directly onto the branch I'm having you pull from,
so if you see anything you don't like, please don't try to use the topic
branches to recreate things yourself.  That will only frustrate you and
get me yelled at.  Let me know what you want removed and I'll fix up a
new branch for you.

Otherwise, it's all typical stuff.  Here's the git boilerplate:
